Fear has evolved to protect organisms from harm. The brain’s amygdala detects threats, while other areas provide context. While some enjoy the thrill of fear due to a sense of control, others may find it overwhelming. Disorders stemming from abnormal fear are prevalent but treatable.
Thinking about the circuitry of the brain and human psychology, some of the main chemicals that contribute to the “fight or flight” response are also involved in other positive emotional states, such as happiness and excitement. So, it makes sense that the high arousal state we experience during a scare may also be experienced in a more positive light.
A part of the brain called the hippocampus is closely connected with the amygdala. The hippocampus and prefrontal cortex help the brain interpret the perceived threat. They are involved in a higher-level processing of context, which helps a person know whether a perceived threat is real.
